TECHNICAL FIELD

The present application relates to the field of communications, forexample, to methods and apparatuses for transmitting and receivingcontrol signaling, and a method for determining information.

BACKGROUND

As one of the core technologies of the 5th generation wireless systems(5G), a high-frequency communication provides strong support for a highspeed and a large bandwidth of the communication in the future. However,a core problem of the high-frequency communication is that the path lossis relatively great. Meanwhile, the size of an antenna is relativelysmall as well. In view of this, multiple antennas may be used forforming a beam to resist the path loss.

To improve system efficiency, resist beam blockage scenarios, fast linkrecovery, and a beam of a downlink signal may be notified by physicallayer dynamic control signaling. In the case where the interval betweenthe control signaling and the downlink signal is less than apredetermined threshold, a terminal cannot acquire the receive beam ofthe downlink signal through information notified by the physical layerdynamic control signaling.

In the related new radio (NR) protocol, in the case where the intervalbetween physical layer dynamic control signaling and a downlink signalis less than a predetermined threshold, a beam of a control resource set(CORESET) having the minimum control resource set identification(CORESET ID) in the closest slot is used for caching data.

There are two situations in the preceding solution. The first situationis that in the case where the interval between the physical layerdynamic control signaling and the downlink signal is less than thepredetermined threshold, the bit field for notifying the beam in thephysical layer dynamic control signaling is not fully utilized. Thesecond situation is that the downlink signal needs to be cached beforethe physical layer dynamic control signaling is decoded; however,actually, the downlink signal may not be scheduled by a base station; ifa terminal needs to cache the dynamically-scheduled potential downlinksignal according to the CORESET with the closest CORESET ID andaccording to a rule and a previously scheduled signal may exist at theposition where the potential downlink signal is located, then in thecase where the beam of the previously scheduled downlink signal and thebeam of the potential downlink signal cannot be generated by theterminal simultaneously, the base station and the terminal need to agreeon the behavior to guarantee the effectiveness of communication.

No effective solution has yet been proposed for the preceding technicalproblem in the related art.

Inthis way, the following defect in the related art is overcome: in thecase where the interval between physical layer dynamic control signalingand a downlink signal is less than a predetermined threshold, the bitfield for notifying a beam in the physical layer dynamic controlsignaling is not fully utilized so that the resource utilization isrelatively low; and the following technical effect is achieved: theresource utilization of the control signaling is improved.

In the case where the type of the first transmission parameter is theTCI, the DL-RSs in the DL-RS set formed by the DL-RSs associated withthe Spatial Rx parameters in each state in the first correspondencemapping table are able to be received by a first communication nodesimultaneously; in the case where the type of the first transmissionparameter is the TCI, the DL-RS set formed by the DL-RSs associated withthe Spatial Rx parameters in each state in the first correspondencemapping table is an empty set. The first communication node is acommunication node for receiving at least one of the first signal or thefirst control signaling.

The present embodiment will be described below by way of example inconjunction with exemplary embodiments.

Exemplary Embodiment One

In the beam-based communication, the beam of a PDSCH may be notified bydownlink control information (DCI). In the case where the intervalbetween the DCI and the PDSCH is less than K, the terminal needs theradio frequency to receive and cache the PDSCH before decoding the DCI,so in the related NR, it is stipulated that in the case where theinterval between the DCI and the PDSCH is less than the predeterminedthreshold K, a QCL parameter of a demodulation reference signal (DMRS)of the PDSCH is acquired according to a QCL parameter corresponding tothe minimum CORESET ID in the closest slot; in the case where theinterval between the DCI and the PDSCH is greater than or equal to thepredetermined threshold K, the QCL parameter of the DMRS of the PDSCH isacquired by using QCL information indicated in the DCI. However, toreduce the complexity of blind detecting a physical downlink controlchannel (PDCCH) by the terminal, the load of the PDCCH in the case wherethe interval between the DCI and the PDSCH is less than K is the same asthe load of the PDCCH in the case where the interval between the DCI andthe PDSCH is greater than or equal to K. In this way, in the case wherethe interval between the DCI and the PDSCH is less than K, the TCInotification field of 3 bits (the TCI notification field is used fornotifying the QCL parameter of the DMRS of the PDSCH) in the DCI existsbut is not used. In the related NR version, the TCI notification fieldoccupies 3 bits. Therefore, the enhanced solution below is proposed.

In the case where the interval between the DCI and the PDSCH is lessthan K, the TCI notification field of 3 bits in the DCI may notify oneor more transmission parameters (that is, the first transmissionparameter), except for the transmission parameter of the TCI, in theDCI, and the transmission parameters in the related NR DCI format_1 areshown in Table 1 in order.

As shown in Table 1, the interval between the DCI and the PDSCH may bedetermined according to information indicated in transmission parameterindicator 5.

For example, the first transmission parameter is the transmissionparameter numbered 14 in Table 1. In the case where the interval betweenthe DCI and the PDSCH is less than K, the PUCCH resource indicator mayindicate one PUCCH resource selected from at most 32 PUCCH resources byusing a total of 5 bits of the bit field numbered 14 and the bit fieldnumbered 17 in Table 1. In an embodiment, in the case where it isdetermined that the PUCCH set is set 0 according to the uplink controlinformation (UCI) load, the indexes of the PUCCH resources in set 0 maybe jointly indicated by using the two bit fields; in the case where itis determined that the PUCCH set is not set 0 according to the UCI load,even though the interval is less than K, the PUCCH resources may benotified only by using the bit field numbered 14 in Table 1 rather thanjointly indicated by using the bit field numbered 14 and the bit fieldnumbered 17 in Table 1 for the reason that the maximum number of thePUCCH resources included in these sets is 8. In the case where theinterval between the DCI and the PDSCH is greater than or equal to K,the PUCCH resources may be indicated in the manner that one PUCCHresource selected from at most 4 PUCCH resources only by using theindicator numbered 14 in Table 1. In the case where the interval betweenthe DCI and the PDSCH is less than K, the sequence of the indicators inthe DCI may follow the sequence in Table 1 and only the indicator 14 andthe indicator 17 jointly form the PUCCH resource indicator.Alternatively, the sequence of the transmission parameter indicators asshown in Table 2 may also be used. Compared with Table 1, in Table 2,the change is that the transmission parameter indicator 17 is canceledand the number of bits of the transmission parameter indicator 14becomes 5 bits.

In this way, in the case where the interval between the DCI and thePDSCH is less than the predetermined threshold K, the dynamic selectionmay be performed on 32 PUCCH resources for the DCI, as shown in Table 3;in the case where the transmission interval between the DCI and thePDSCH is greater than or equal to the predetermined threshold K, thedynamic selection may be performed on only 4 PUCCH resources for theDCI, as shown in Table 4.

TABLE 4 Indication Value of PUCCH Resource Selection Parameter in DCIPUCCH Resource 0 PUCCH resource 1 1 PUCCH resource 2 2 PUCCH resource 33 PUCCH resource 4

In Table 3 and Table 4, 4 PUCCH resources in Table 4 are the same as thefirst 4 PUCCH resources in Table 3. In this way, when the base stationperforms notification, only 32 PUCCH resources need to be notified. Ofcourse, the present embodiment does not exclude the case where the PUCCHresources in Table 3 are different from the PUCCH resources in Table 4.In this way, when the base station performs notification by usinghigh-layer signaling, the PUCCH resources in Table 3 and Table 4 arenotified separately.

In the present embodiment, the interval between the DCI and the PDSCHmay be at least one of the following intervals: the interval between theending time-domain symbol of the DCI and the starting time-domain symbolof the PDSCH; the interval between the starting time-domain symbol ofthe DCI and the starting time-domain symbol of the PDSCH; the intervalbetween the latest time-domain symbol in the ending symbols of theCORESET in the slot where the DCI is located and the startingtime-domain symbol of the PDSCH; the interval between the earliesttime-domain symbol of the CORESET in the slot where the DCI is locatedand the starting time-domain symbol of the PDSCH; the interval betweenthe ending time-domain symbol of the DCI and the starting time-domainsymbol in each of multiple slots occupied by the PDSCH; or the intervalbetween the starting time-domain symbol of the DCI and the startingtime-domain symbol in each of multiple slots occupied by the PDSCH.

In the preceding description, in the case where the interval between theDCI and the PDSCH is less than the predetermined threshold K, the TCIfield is used for the indication of the PUCCH resources. Similarly, itis also possible that in the case where the interval between the DCI andthe PDSCH is less than a predetermined threshold, the TCI field is usedfor the rate mating indicator. Similarly, when the rate matinginformation is configured through the high-layer signaling, two sets ofrate mating parameters need to be configured, such as one set ofparameters used for establishing a table similar to Table 3 and theother set of parameters used for establishing a table similar to Table4. Alternatively, one set of parameters is used, all entries in this setof parameters are used for establishing a table similar to Table 3, andthe agreed part of entries (such as the first M entries or the last Mentries) are used for establishing a table similar to Table 4. In thiscase, Table 3 and Table 4 show the correspondence between the indexvalues and the rate mating information, and the number of states inTable 3 and the number of states in Table 4 changes. For example, thehigh-layer-configured rate-match-PDSCH-resource-set includes 2resources; in the case where the interval between the DCI and the PDSCHis less than the predetermined threshold, the rate mating information isobtained with reference to Table 5, and there are 2⁽¹⁺³⁾=16 index valuesin Table 5 in total, where the index values are jointly indicated by thetransmission parameter indicator 8 and the transmission parameterindicator 17 in Table 1; in the case where the transmission timeinterval between the DCI and the PDSCH is greater than or equal to thepredetermined threshold, the rate mating information is obtained withreference to Table 6, and there are 2⁽¹⁾=2 states in Table 6, where thestates are indicated by the transmission parameter indicator 8 in Table1.

Similarly, in the case where the interval between the DCI and the PDSCHis less than the predetermined threshold K, a TCI field may be used forone or more transmission parameters in 20 parameters except for thetransmission parameter of the TCI in Table 1. For example, in the casewhere the interval between the DCI and the PDSCH is less than thepredetermined threshold K, the first bit in the 3 bits of the TCI fieldis used for the notification of the rate mating information and the last2 bits are used for the notification of zero power channel stateinformation reference signal (ZP-CSI-RS) information. Alternatively, inthe case where the interval between the DCI and the PDSCH is less thanthe predetermined threshold, the type of the transmission parameterindicated by the TCI field or the type of the transmission parameterindicated by each bit of the TCI field is determined according to anagreed rule or signaling information. For example, the base stationindicates through signaling that in the case where the interval betweenthe DCI and the PDSCH is less than the predetermined threshold K, thefirst bit of the TCI field is used for the notification of the ratemating information and the last 2 bits of the TCI field are used for thenotification of the ZP-CSI-RS information. Alternatively, the basestation indicates through signaling that in the case where the intervalbetween the DCI and the PDSCH is less than the predetermined thresholdK, all the 3 bits of the TCI field are used for the notification of therate mating information. Alternatively, the base station notifiesthrough the signaling that in the case where the interval between theDCI and the PDSCH is less than the predetermined threshold K, the first2 bits of the TCI field are used for the notification of the PDSCHfrequency-domain resource and the last 1 bit of the TCI field is usedfor the notification of the ZP-CSI-RS information.

In the preceding embodiment, in the case where the interval between theDCI and the PDSCH is less than K, the TCI field is used for indicatingtransmission parameters of other types except for the transmissionparameter of the TCI in Table 1, and may also be used for indicatingtransmission parameter types which do not exist in Table 1. For example,the TCI field is used for indicating CSI information (where the CSIinformation is used for triggering the reporting of at least one ofaperiodic CSI-RS or aperiodic CSI). In this way, in the case where theinterval between the DCI and the PDSCH is less than K, the TCI field inthe DCI is used for indicating CSI triggering information; in the casewhere the interval between the DCI and the PDSCH is greater than K, theTCI field is used for indicating TCI information, and in this case, theCSI information cannot be indicated in the DCI.

Exemplary Embodiment Two

In this embodiment, according to a relationship between the transmissioninterval between the physical layer dynamic control signaling and thefirst signal and the predetermined threshold, at least one piece of thefollowing information is determined: a transmission parameter typeindicated by a specified indicator of the physical layer dynamic controlsignaling or whether the physical layer dynamic control signalingincludes indication information indicating a specified transmissionparameter type.

In an embodiment, in the case where the relationship between thetransmission time interval between the first control signaling and thefirst signal and the predetermined threshold K is relationship one, thespecified indicator of the physical layer dynamic control signaling isused for indicating a first type of transmission parameter; in the casewhere the relationship between the transmission time interval betweenthe first control signaling and the first signal and the predeterminedthreshold K is relationship two, the specified indicator of the physicallayer dynamic control signaling is used for indicating a second type oftransmission parameter.

In an embodiment, in the case where the relationship between thetransmission time interval between the first control signaling and thefirst signal and the predetermined threshold K is the relationship one,the physical layer dynamic control signaling includes the indicationinformation indicating the specified transmission parameter type; in thecase where the relationship between the transmission time intervalbetween the first control signaling and the first signal and thepredetermined threshold K is the relationship two, the physical layerdynamic control signaling does not include the indication informationindicating the specified transmission parameter type.

In an embodiment, the relationship one is that the transmission intervalbetween the physical layer dynamic control signaling and the firstsignal is less than the predetermined threshold, and the relationshiptwo is that the transmission interval between the physical layer dynamiccontrol signaling and the first signal is greater than or equal to thepredetermined threshold. Alternatively, the relationship one is that thetransmission interval between the physical layer dynamic controlsignaling and the first signal is less than or equal to thepredetermined threshold, and the relationship two is that thetransmission interval between the physical layer dynamic controlsignaling and the first signal is greater than the predeterminedthreshold.

In an embodiment, the transmission parameter may be the transmissionparameter of the first signal or the transmission parameter of thesecond signal.

In an embodiment, in the case where the transmission time intervalbetween the DCI and the PDSCH (the first signal) is less than K, theindicator numbered 17 in the DCI in Table 1 is used for indicating ratemating indication information; in the case where the transmission timeinterval between the DCI and the PDSCH is greater than or equal to K,the indicator numbered 17 in the DCI in Table 1 is used for indicatingTCI information.

Alternatively, in the case where the transmission time interval betweenthe DCI and the PDSCH (the first signal) is less than K, the indicatornumbered 17 in the DCI in Table 1 is used for indicating CSI requestinformation; in the case where the transmission time interval betweenthe DCI and the PDSCH is greater than or equal to K, the indicatornumbered 17 in the DCI in Table 1 is used for indicating the TCIinformation (that is, information about the QCL parameter of the DMRS ofthe PDSCH). That is, in the case where the interval between the DCI andthe PDSCH is less than K, the DCI of DL-Grant includes CSI requestindication information; in the case where the interval between the DCIand the PDSCH is greater than or equal to K, the DCI of DL-Grant doesnot include the CSI request indication information.

Exemplary Embodiment Three

In the preceding exemplary embodiment one and exemplary embodiment two,the number of candidate parameter values included in the value set ofthe first transmission parameter changes according to the firstrelationship. For example, in the case where the interval between theDCI and the PDSCH is less than K, the value set of the firsttransmission parameter includes X1 values; in the case where theinterval between the DCI and the PDSCH is greater than K, the value setof the first transmission parameter includes X2 values. Alternatively,in the case where the interval between the DCI and the PDSCH is lessthan K, the correspondence mapping table between the index valuereferenced by the index value of the first transmission parameterindicated by the control signaling in the DCI and the first transmissionvalue is table one (such as Table 3); in the case where the intervalbetween the DCI and the PDSCH is greater than K, the correspondencemapping table between the index value referenced by the index value ofthe first transmission parameter indicated by the control signaling inthe DCI and the first transmission value is table two (such as Table 4).

In an embodiment, whether the TCI field exists in the DCI is alsoconfigured by per CORESET. It is configured that the TCI field does notexist in the DCI in CORESET1, that is, the DCI in the CORESET1 does notinclude the transmission parameter indicator numbered 17 in Table 1. Itis configured that the TCI field exists in the DCI in CORESET2, that is,the DCI in the CORESET2 includes the transmission parameter indicatornumbered 17 in Table 1. Moreover, it is agreed that in the case wherethe transmission interval between the DCI and the PDSCH is less than anagreed threshold (such as K), the TCI field in the DCI is used forindicating the rate mating information. Therefore, the index valuereferenced by the rate mating information indicated in the DCItransmitted in the CORESET2 and the rate mating information are shown intwo tables, Table 5 and Table 6. In the case where the interval betweenthe DCI and the PDSCH is less than the predetermined threshold, Table 5is referenced; in the case where the interval between the DCI and thePDSCH is greater than or equal to the predetermined threshold, Table 6is referenced, and the index value referenced by the rate matinginformation indicated in the DCI in the CORESET1 and rating informationalso reference Table 6. Alternatively, the index value referenced by therate mating information indicated in the DCI in the CORESET1 and therating information reference a table different from Table 6, such asTable 6-2, that is, in this case, there are three tables referenced bythe rate mating information. In this way, when the base station notifiesthe rate mating information through high-layer signaling, the basestation needs to notify the rate mating information for each table, orthe high layer notifies the information of Table 6 and Table 5 throughone piece of signaling and notifies the information of Table 6-2 throughanother piece of signaling.

That is, in the case where the transmission interval between the DCI andthe PDSCH is less than K, the table referenced by the index informationof the rate mating information indicated in the DCI is Table 5. In othercases, the table referenced by the index information of the rate matinginformation indicated in the DCI is Table 6. In the case where the TCIfield does not exist in the DCI, the table referenced by the indexinformation of the rate mating information indicated in the DCI is Table6, or the table referenced by the index information of the rate matinginformation indicated in the DCI is Table 6-2.

In the preceding implementation, there are Y tables referenced by therate mating information indicated in the DCI. Similarly, there may be Ytables referenced by other transmission parameter types indicated in theDCI. Y is a number greater than 1, such as Y=2 or Y=3 in the precedingimplementation.

Exemplary Embodiment Four

In the preceding embodiment, the second information is determinedaccording to the first information. The second information includes atleast one piece of the following information: the number N of bits usedin the control signaling to notify the first transmission parameter, thecorrespondence table between the referenced index value for notifyinginformation about first transmission parameter in the control signalingand the value of the first transmission parameter, the type of the firsttransmission parameter notified by the predetermined indication field inthe control signaling, or position information of the bits used in thecontrol signaling to notify the first transmission parameter. The firstinformation includes the relationship between the transmission timeinterval between the control signaling and the first signal and thepredetermined threshold.

In this embodiment, the first information further includes at least onepiece of the following information from information one to informationten.

Information one: Information included in the second control signaling.For example, the base station transmits the signaling information to theterminal and in the signaling information, at least one piece of thefollowing information is notified: whether the TCI field may be used forthe notification of other transmission parameter types, the transmissionparameter type that the TCI field is able to be used for notifying, orthe transmission parameter type which bit of the TCI field is able to beused for notifying. The information notified in the second controlsignaling is used for determining the second information.

Information two: TCI-PresentInDCI parameter associated with the CORESETwhere the first control signaling is located. The TCI-PresentInDCI isused for configuring whether the TCI field exists in the DCI of theDL-Grant transmitted in the CORESET, that is, whether the indicatornumbered 17 in Table 1 exists. For example, in the case where theTCI-PresentInDCI associated with the CORESET is not enabled, the TCIfield does not exist in the DCI in the CORESET and the number of thebits used by the first transmission parameter does not change as whetherthe transmission time interval between the DCI and the PDSCH is lessthan the predetermined threshold K.

Information three: Whether the carrier frequencies where the signal islocated are less than the predetermined threshold K. For example, in thecase where the PDSCH is below 6 GHz, the mechanism in which the secondinformation is determined according to the first information is notinitiated. Alternatively, information three: the terminal transmits thefrequency domain range that the terminal is able to process, and in thecase where the capability of the terminal to process the frequencydomain is FR1 (that is, the frequency domain range that the terminal isable to process is less than the predetermined threshold, such as lessthan 6 GHz), the mechanism in which the second information is determinedaccording to the first information is not initiated.

Information four: Whether at least one CORESET configured with SpatialRx parameters exists in a CORESET set required to be detected by thefirst communication node. For example, in the case where the CORESETconfigured with the Spatial Rx parameters does not exist in the CORESETset required to be detected by the terminal, the mechanism in which thesecond information is determined according to the first information isnot initiated.

Information five: Whether at least one CORESET configured with SpatialRx parameters exists in a CORESET set associated with a dedicated searchspace required to be detected by the first communication node. Forexample, in the case where the CORESET configured with the Spatial Rxparameters does not exist in the CORESET set associated with thededicated search space required to be detected by the terminal, themechanism in which the second information is determined according to thefirst information is not initiated.

Information six: Whether the CORESET having the minimum CORESET ID inthe time unit closest to the signal is configured with Spatial Rxparameters. For example, in the case where the CORESET having theminimum CORESET ID in the time unit closest to the PDSCH/aperiodicCSI-RS (AP-CSI-RS) is not configured with the Spatial Rx parameters, themechanism in which the second information is determined according to thefirst information is not initiated.

Information seven: Whether the CORESET having the minimum CORESET ID inthe time-domain symbol closest to the signal is configured with SpatialRx parameters. For example, in the case where the CORESET having theminimum CORESET ID in the time-domain symbol closest to thePDSCH/AP-CSI-RS is not configured with the Spatial Rx parameters, themechanism in which the second information is determined according to thefirst information is not initiated.

Information eight: Whether at least one TCI state exists in the TCIstate pool associated with the signal. The QCL parameter correspondingto the RS set in the TCI state includes the Spatial Rx parameter. Forexample, in the case where a TCI state does not exist in TCI state pool1 configured by the RRC associated with the PDSCH, and the QCL parametercorresponding to one DL-RS in the TCI state includes the Spatial Rxparameter, the mechanism in which the second information is determinedaccording to the first information is not initiated.

Information nine: Whether at least one TCI state exists in theactivation TCI state pool associated with the signal. The QCL parametercorresponding to the RS set in the TCI state includes the Spatial Rxparameter. For example, in the case where a TCI state does not exist inthe MAC-CE activation TCI state pool associated with the PDSCH or theTCI state pool formed by the TCI states that the TCI field in the DCI isable to indicate, and the QCL parameter corresponding to one DL-RS inthe TCI state includes the Spatial Rx parameter, the mechanism in whichthe second information is determined according to the first informationis not initiated.

Information ten: Information about the capability of processing thefrequency domain range reported by the first communication node. Forexample, in the case where the frequency domain range that the terminalis able to process reported by the terminal is FR1 (that is, thefrequency domain range which is able to be processed is less than 6GHz), the mechanism in which the second information is determinedaccording to the first information is not initiated; in the case wherethe frequency domain range that the terminal is able to process reportedby the terminal is FR2 (that is, the frequency domain range which isable to be processed is greater than or equal to 6 GHz), the mechanismin which the second information is determined according to the firstinformation is initiated.

Exemplary Embodiment Five

In this embodiment, the table referenced by the TCI field notified inthe DCI is determined according to the relationship between the intervalbetween the DCI and the PDSCH and the predetermined threshold K.

In an embodiment, in the case where the interval between the DCI and thePDSCH is less than the predetermined threshold K, the table referencedby the TCI in the DCI is Table 7; in the case where the interval betweenthe DCI and the PDSCH is greater than or equal to the predeterminedthreshold K, the table referenced by the TCI in the DCI is Table 8. TCIstate 10 to TCI state 17 and TCI state 20 to TCI state 27 are configuredby different high-layer control signaling. The high-layer controlsignaling includes at least one of RRC signaling or MAC-CE signaling.

In an embodiment, in the case where the interval between the DCI and thePDSCH is less than K, the Spatial Rx parameter of the DMRS of the PDSCHis obtained according to an agreed rule (for example, the Spatial Rxparameter of the DMRS of the PDSCH is acquired according to theconfiguration of the Spatial Rx parameter of the CORESET having theminimum CORESET ID in the closest slot), and other QCL parameterinformation of the DMRS of the PDSCH is obtained according to the TCIfield in the DCI and with reference to Table 7. Alternatively, all QCLparameters of the DMRS of the PDSCH are obtained according toinformation indicated by the TCI field in the DCI and with reference toTable 7, and the configuration of Table 7 is limited. In the case wherethe interval between the DCI and the PDSCH is greater than or equal toK, all QCL parameters of the DMRS of the PDSCH are obtained according toinformation indicated by the TCI field in the DCI and with reference toTable 8.

One state is used for establishing an association relationship between QDMRS groups of the PDSCH and Q DL-RS sets, where Q is an integer greaterthan or equal to 1. As shown in Table 9, the association between (DMIRSgroup1, DL-RS set1) and (DMRS group2, DL-RS set2) is established in TCIstate-n, where DL-RS set1 includes {DL-RS1, DL-RS2}, and DL-RS set2includes DL-RS3. In DMRS group1, a QCL relationship exists with respectto the QCL parameter in QCL-type1 and DL-RS 1, and each QCL-Typeincludes at least one of the following parameters: a Doppler shift, aDoppler spread, an average delay, a delay spread, an average gain, or aSpatial Rx parameter. The DL-RS may be the CSI-RS/Synchronization Signaland physical broadcast channel (PBCH) block (SSB)/DMRS of a PBCH, wherethe DMRS group may be referred to as a QCL target reference signal andthe DL-RS may also be referred to as a QCL reference signal.

TABLE 9 TCI State-n DMRS group 1 (DL-RS 1, QCL-Type 1) (DL-RS 2,QCL-Type 2) DMRS group 2 (DL-RS 3, QCL-Type 1)

In an embodiment, the QCL-Type associated with each TCI state in Table 7includes the Spatial Rx parameter, and the DL-RS set formed by this QCLparameter has a predetermined restriction condition. The restrictioncondition includes at least one of the following: this DL-RS setincludes only one DL-RS; each two DL-RSs in this set are of QCL withrespect to the Spatial Rx parameters; the DL-RSs in this set may bereceived by the terminal simultaneously; this DL-RS set is an empty set;or the DL-RSs in this set belong to one group, where the group may beallocated by the base station, or may be reported by the terminal. In anembodiment, for example, the associated QCL-Type in 8 states in Table 7includes the DL-RSs of the Spatial Rx parameter, which includes{DL-RS100, DL-RS101, DL-RS102, DL-RS103, DL-RS104, DL-RS105, DL-RS106,DL-RS107} (that is, the DMRS group in state i and DL-RS 10i satisfy theQCL relationship with respect to at least the Spatial Rx parameter,where i=0, 1, . . . , 7). Each two DL-RSs in this set are of QCL withrespect to the Spatial Rx parameters, or these DL-RSs may be received bythe terminal simultaneously, or all the DL-RSs of the Spatial Rxparameter included in the associated QCL-Type in the 8 states in Table 7are DL-R100, or all the QCL-Types associated with the DL-RSs in the 8states in Table 7 do not include the Spatial Rx parameter. In this case,it is agreed that the Spatial Rx parameter of the DMRS of the PDSCH isobtained according to an agreed rule, for example, it is agreed that inthis case, the DMRS of the PDSCH and the DMRS in the minimum CORESET IDare of QCL with respect to the Spatial Rx parameter.

In an embodiment, in the case where the interval between the DCI and thePDSCH is less than the predetermined threshold K, the table referencedby the TCI field included in the DCI is Table 7; in the case where theinterval between the DCI and the PDSCH is greater than or equal to thepredetermined threshold K, the table referenced by the TCI field in theDCI is Table 8. The configuration of the DL-RSs associated with theSpatial Rx parameter in the TCI state in Table 7 is limited, that is,one or a finite number of beams associated with these TCI states exist,so that in this case, the terminal has not decoded the DCI, and theterminal needs to know the Spatial Rx parameter of the PDSCH before theDCI is decoded. However, in Table 8, such limit does not exist.Therefore, both Table 7 and Table 8 are required.

The configuration of Table 7 is configured through the high-layersignaling. In order to implement that different beams may be used atdifferent times, even though the transmission time interval between theDCI and the PDSCH is less than K, multiple Tables 7 may be configured.The effective time-domain pattern of each Table 7 is configured. Forexample, a period and a period offset of Table 7-1 are configured, and aperiod and a period offset of Table 7-2 are configured. Alternatively,there are two Tables 7, Table 7-1 and Table 7-2. The period and theperiod offset of Table 7-1 are configured. For other slots, Table 7-2 isreferenced. That is, in the case where the DCI falls into the slot shownin Table 7-1, the TCI field notified in the DCI references Table 7-1; inthe case where the DCI falls into other slots, the TCI field notified inthe DCI references Table 7-2. Alternatively, three Tables 7 may beconfigured such as Table 7-1, Table 7-2, and Table 7-3, the period andthe period offset of Table 7-1 are configured, the period and the periodoffset of Table 7-2 may also be configured, and a period and a periodoffset of Table 7-3 are not configured. In the case where the DCI fallsinto the slot where Table 7-1 is located, the TCI field in the DCIreferences Table 7-1; in the case where the DCI falls into the slotwhere Table 7-2 is located, the TCI field in the DCI references Table7-2; in the case where the DCI falls into other slots, the TCI field inthe DCI references Table 7-3. To sum up, in the case where the intervalbetween the DCI and the PDSCH is less than the predetermined threshold,the QCL information of the PDSCH is obtained according to the TCIindication information indicated in the DCI and with reference to thetable referenced by the corresponding TCI in the slot where the PDSCH islocated. FIG. 5 shows the time-domain patterns corresponding to Table7-1 to Table 7-3. In the case where the PDSCH falls into slot n and theinterval between the PDSCH and the DCI is less than the predeterminedthreshold K, the QCL parameter of the DMRS of the PDSCH is obtainedaccording to the TCI information indicated in the DCI and with referenceto Table 7-1; in the case where the PDSCH falls into slot n+1 and theinterval between the PDSCH and the DCI is less than the predeterminedthreshold K, the QCL parameter of the DMRS of the PDSCH is obtainedaccording to the TCI information indicated in the DCI and with referenceto Table 7-2; in the case where the PDSCH falls into slot n and theinterval between the PDSCH and the DCI is greater than or equal to thepredetermined threshold K, the QCL parameter of the DMRS of the PDSCH isobtained according to the TCI information indicated in the DCI and withreference to Table 8.

Similarly, the table corresponding to the TCI parameter of the AP-CSI-RSis determined according to the relationship between the interval betweenthe DCI and the AP-CSI-RS and the predetermined threshold.

In an exemplary embodiment, the TCI indication information is used forindicating the QCL relationship between the DMRS group/CSI-RS port groupand the DL-RS set, that is, one piece of TCI index informationcorresponds to one state; one state includes the correspondence betweenQ DMRS groups and Q DL-RS sets; one DL-RS set includes one or moreDL-RSs; and each DL-RS associates with one QCL parameter set, indicatingthat the reference signal in the DMRS group/CSI-RS port group and oneDL-RS in the DL-RS set associated with the DMRS group/CSI-RS port groupsatisfy the QCL relationship with respect to the QCL parameter set. Tworeference signals satisfy the QCL relationship with respect to one QCLparameter, indicating that the QCL parameter of one reference signal maybe acquired through the QCL parameter of two reference signals. The QCLparameter includes at least one of the following parameters: a Dopplershift, a Doppler spread, an average delay, a delay spread, an averagegain or a Spatial Rx parameter.

In this exemplary embodiment, two reference signals are of QCL,indicating that the two reference signals are of QCL with respect to atleast the Spatial Rx parameter and whether the two reference signals areof QCL with respect to other QCL parameters is not limited.

In an exemplary embodiment, a channel may also be a signal, that is, thesignal is transmitted in the channel. For example, a data signal istransmitted in a data channel.

In an exemplary embodiment, different CCs may be associated throughdifferent serving cell IDs.

In this embodiment, a method for receiving control signaling is furtherprovided. FIG. 9 is a flowchart of a method for transmitting controlsignaling according to an embodiment of the present application. Asshown in FIG. 9 , this process includes step S902 and step S904described below.

In step S902, second information is determined according to firstinformation.

In step 904, first control signaling is received according to the secondinformation.

The second information includes at least one of the following: thenumber N of bits used in a first control signaling to notify a firsttransmission parameter, a correspondence mapping table between an indexvalue referenced by the first transmission parameter in the firstcontrol signaling and the value of the first transmission parameter, thetype of the first transmission parameter notified by a predeterminedindication field in the first control signaling, or position informationof the bits used in the first control signaling to notify the firsttransmission parameter; and the first information includes arelationship between a transmission time interval between the firstcontrol signaling and a first signal and a predetermined threshold K,where N and K are non-negative integers.

In an embodiment, the predetermined threshold is equal to the secondpredetermined threshold, where the QCL parameter of the second signal isdetermined according to the relationship between the interval betweenthe second signal and the control information scheduling the secondsignal and the second predetermined threshold.

In an embodiment, in the related NR, it is stipulated that in the casewhere the interval between the DCI and the PDSCH is less than thepredetermined threshold K, the PDSCH is received by using the Spatial Rxparameter of the minimum CORESET ID in the closest slot. When theterminal caches the PDSCH, the DCI is not decoded so that the PDSCHneeds to be cached by using a known beam. The PDSCH may be stored at anyposition in a time window of K time-domain symbols after the DCI. Inthis case, the terminal needs to cache PDSCHs in the time window of theK time-domain symbols after the DCI by using the beam in the minimumCORESET ID. However, it is possible that these potential PDSCHs do notexist actually, and the terminal still needs to cache these PDSCHs. Theproblem is that if a periodic CSI-RS exists in this time window and aSpatial Rx parameter of the periodic CSI-RS are different from a SpatialRx parameter of the PDSCH required to be cached by the terminal, thepriority between the Spatial Rx parameter of the periodic CSI-RS and theSpatial Rx parameter of the PDSCH required to be cached by the terminalneeds to be determined.

In manner one, the base station and the terminal agree that at least oneof the Spatial Rx parameter of the downlink signal or the Spatial Rxparameter of the downlink channel in this time window is determinedbased on the Spatial Rx parameter of the CORESET having the minimumCORESET ID, and other QCL parameters of at least one of the downlinksignal or the channel are also determined based on the minimum CORESETID, or other QCL parameters are obtained according to configurationinformation of the downlink signal or the channel, for example, otherQCL parameters are obtained according to the configuration informationof the QCL parameter in the configuration information of the periodicCSI-RS.

In manner two, the base station and the terminal agree that in the casewhere the interval between the periodic CSI-RS and the CORESET havingthe minimum CORESET ID in the closest slot is less than thepredetermined threshold K, the priority of the QCL parameter which is atleast a Spatial Rx parameter of the periodic CSI-RS is higher than thepriority of the Spatial Rx parameter of the potential PDSCH in the sametime-domain symbol; in the case where the interval between the periodicCSI-RS and the CORESET having the minimum CORESET ID in the closest slotis greater than or equal to the predetermined threshold K, the priorityof the Spatial Rx parameter of the PDSCH in the same time-domain symbolis higher than the priority of the Spatial Rx parameter of the CSI-RS inthe same time-domain symbol.

As shown in FIG. 2 , the CORESET having the minimum CORESET ID in a slotclosest to the periodic CSI-RS in slot n is CORESET 0 in slot n. In thecase where the PDSCH and the CSI-RS in slot n are in the sametime-domain symbol, the CSI-RS and the PDSCH are received by using thebeam of the CSI-RS, that is, in this case, the priority of the SpatialRx parameter of the PDSCH is lower than the priority of the Spatial Rxparameter of the periodic CSI-RS. In this case, in the case where thesymbol of the periodic CSI-RS does not exist in slot n, in one manner,the PDSCH is received by using the Spatial Rx parameter of the periodicCSI-RS so that the number of times of switching the beam by the terminalin slot n is reduced; or the terminal and the base station agree that inthe case where the time-domain symbol of the CSI-RS does not exist inslot n, the PDSCH is received by using the beam of the CORESET closestto the PDSCH, as shown in FIG. 3 .

The minimum CORESET ID in the slot closest to the periodic CSI-RS inslot n+2 is still CORESET0 in slot n (in slot n+1 and slot n+2, theterminal does not need to detect the CORESET). In this case, theinterval between the periodic CSI-RS in slot n+2 and CORESET0 is greaterthan the predetermined threshold, and in slot n+2, if the PDSCH and theCSI-RS are in the same time-domain symbol, then the PDSCH and the CSI-RSare received by using the beam of the PDSCH. That is, in this case, thepriority of the Spatial Rx parameter of the PDSCH is higher than thepriority of the Spatial Rx parameter of the periodic CSI-RS.Alternatively, in slot n+2, in the case where the receive beam of thePDSCH and the receive beam of the CSI-RS conflicts, where the PDSCH andthe CSI-RS are in the same time-domain symbol, the measurement of theCSI-RS is given up. In slot n, when the terminal needs to cache thePDSCH scheduled by CORESET0, the DCI is not decoded, so that the PDSCHmay be not exist, and then in this case, the periodic CSI-RS needs to bereceived in priority; in slot n+2, the terminal has decoded the DCIcorresponding to the PDSCH that the terminal needs to cache, and then inthis case, the PDSCH is determined by the terminal as having beenscheduled by the base station.

In this embodiment, the second information is determined according tothe first information, where the second information includes at leastone piece of the following information: the QCL parameter of the firstsignal, whether a control channel is detected in the first signal,whether the first signal is received, or the time-domain symbol positionwhere the first signal is able to be located; and the first informationincludes the following information: whether the second signal exists ina predetermined time window after the specified CORESET.

In an embodiment, the specified CORESET satisfies at least one of thefollowing characteristics: the CORESET is a CORESET having the minimumCORESET ID in a time-domain symbol closest to the second signal; thespecified CORESET is a CORESET having the minimum CORESET ID in a slotclosest to the second signal; in the CORESET, the terminal needs todetect at least one piece of DCI scheduling a downlink signal or achannel; the CORESET is a CORESET having the minimum CORESET ID in atime-domain symbol closest to the first signal; or the specified CORESETis a CORESET having the minimum CORESET ID in a slot closest to thefirst signal.

In an embodiment, the first signal includes at least one of thefollowing signals: an aperiodic downlink measurement reference signal, adownlink data channel signal scheduled by physical layer dynamic controlsignaling, a downlink signal scheduled by physical layer dynamic controlsignaling, or a downlink physical control channel signal.

In an embodiment, the second signal satisfies at least one of thefollowing characteristics: the second signal is a previously scheduledsignal; the second signal is a periodic downlink measurement referencesignal; the second signal is an aperiodic downlink measurement referencesignal, where the interval between the DCI scheduling an aperiodicmeasurement reference signal and the aperiodic measurement referencesignal is greater than or equal to a predetermined threshold; the secondsignal is a semi-continuous PDSCH, where the interval between the DCIfor activating semi-persistent scheduling PDSCH (SPS-PDSCH) and theSPS-PDSCH is greater than or equal to the predetermined threshold; orthe second signal is a dynamically-scheduled PDSCH, where the intervalbetween the DCI dynamically scheduling the PDSCH and the PDSCH isgreater than or equal to the predetermined threshold.

In an embodiment, in the case where the second signal exists in thepredetermined time window after the specified CORESET, the QCL parameterof the first signal is acquired according to the QCL parameter of thesecond signal; in the case where the second signal does not exist in thepredetermined time window after the specified CORESET, the QCL parameterof the first signal is not acquired according to the QCL parameter ofthe second signal.

In an embodiment, in the time-domain symbol where the second signal islocated, it is agreed with a second communication node that the firstsignal does not exist.

In an embodiment, in the time-domain symbol where the second signal islocated, it is agreed with the second communication node that thecontrol channel is not detected in the first signal.

In an embodiment, the Spatial Rx parameter of the second signal and theSpatial Rx parameter of the first signal are different, or the spatialfilter corresponding to the Spatial Rx parameter of the second signaland the spatial filter corresponding to the Spatial Rx parameter of thefirst signal are unable to be generated by the first communication nodesimultaneously.

In an embodiment, the second signal and the first signal belong todifferent CCs.

In an embodiment, as shown in FIG. 1 a , in slot n, the base stationschedules PDSCH1 for the terminal, where the interval between DCIscheduling PDSCH1 (the DCI is in CORESET1 in FIG. 1 a ) and PDSCH1 isgreater than the predetermined threshold K, so that in slot n, theterminal certainly knows that in slot n, the base station has scheduledPDSCH1 and then a QCL parameter of PDSCH1 may be acquired throughinformation indicated in the DCI scheduling PDSCH1. In slot n, theterminal further needs to continue to detect at least one of CORESET0 orCORESET2. DCI in CORESET0 or CORESET2 may be used for scheduling PDSCH2for the terminal. For example, PDSCH2 and PDSCH1 may be in differentCCs, since while the potential PDSCH2 is received, the terminal has notdecoded the DCI scheduling PDSCH2, according to the rule, the potentialPDSCH2 needs to be received by using the beam of the minimum CORESET IDin all CCs in slot n, for example, PDSCH2 is received by using the beamof CORESET0. In the case where the dynamically-indicated receive beam(through the Spatial Rx parameter indicated in the DCI) of PDSCH1 andthe beam of CORESET0 are different, the priority between the Spatial Rxparameter of PDSCH1 and the Spatial Rx parameter of PDSCH2 needs to bedetermined. Since PDSCH1 is determined to be scheduled and PDSCH2 maynot exist, the beam of PDSCH1 is used in priority for receiving thepotential PDSCH1 and PDSCH2.

As shown in FIG. 1 b , in slot n, the base station schedules anaperiodic measurement reference signal (CSI-RS) for the terminal, wherethe interval between the DCI scheduling the aperiodic CSI-RS and theaperiodic measurement reference signal is greater than the predeterminedthreshold K. In slot n, the terminal further needs to detect CORESET0.CORESET0 may be used for scheduling the PDSCH for the terminal in slotn, and then in the case where the PDSCH and the CSI-RS in slot n are inthe same time-domain symbol, the priority between the QCL parameter ofthe PDSCH and the QCL parameter of the CSI-RS needs to be determined.Similarly, since the aperiodic measurement reference signal isdetermined to be scheduled, the terminal receives the CSI-RS and thepotential PDSCH by using the aperiodic measurement reference signal atleast in the time-domain symbol where the CSI-RS is located. In the casewhere the time-domain symbol of the aperiodic measurement referencesignal does not exist in slot n, the QCL parameter of the potentialPDSCH may be acquired by using the QCL parameter of the CORESET havingthe minimum CORESET ID in slot n, or it is stipulated that in slot n, inthe time-domain symbol where the potential PDSCH is located, PDSCHs arereceived by using the receive beam of the aperiodic CSI-RS.

It can be seen from FIG. 1 a and FIG. 1 b that even though the intervalbetween the PDSCH and the DCI scheduling the PDSCH is less than thepredetermined threshold K, the QCL parameter of the PDSCH is notnecessarily acquired by using the QCL parameter of the CORESET havingthe minimum CORESET ID closest to the PDSCH, and whether the secondsignal exists in the time-domain symbol where the PDSCH is located alsoneeds to be considered. In the case where the second signal exists inthe time-domain symbol where the PDSCH is located, at least the SpatialRx parameter of the first signal is determined according to the SpatialRx parameter of the second signal; in the case where the second signaldoes not exist in the time-domain symbol where the PDSCH is located, theQCL parameter of the PDSCH is acquired according to the QCL parameter ofthe CORESET having the minimum CORESET ID closest to the PDSCH, wherethe QCL parameter at least includes the Spatial Rx parameter.

As shown in FIG. 1 c , in the case where the interval between the PDSCHand the DCI scheduling the PDSCH is less than the predeterminedthreshold K, at least the Spatial Rx parameter of the PDSCH is acquiredaccording to the Spatial Rx parameter of the minimum CORESET ID in thetime-domain symbol closest to the PDSCH (that is, the Spatial Rxparameter of the PDSCH is acquired according to the Spatial Rx parameterof CORESET1) rather than according to the Spatial Rx parameter of theCORESET having the minimum CORESET ID in the slot closest to the PDSCH,that is, the Spatial Rx parameter of the PDSCH is acquired not accordingto the Spatial Rx parameter of CORESET0.

As shown in FIG. 1 d , in the case where the interval between the PDSCHand the DCI scheduling the PDSCH is less than the predeterminedthreshold K, the PDSCH needs to be receive by using the receive beam ofthe CORESET in the slot closest to the PDSCH, and the potential PDSCHmay be stored in any time-domain symbol in the slot. In this way, in thetime-domain symbol where CORESET1 is located, the potential PDSCH andCORESET1 need to be received simultaneously. In the case where thereceive beam of CORESET1 and the receive beam of CORESET0 are differentor the terminal cannot generate these two receive beams simultaneously,the priority between these two receive beams needs to be determined. Inone manner, it is stipulated that the potential PDSCH in CORESET1 andCORESET1 are of QCL with respect to at least the Spatial Rx parameter.In the other manner, it is stipulated that the PDSCH does not exist inCORESET1, where the interval between the PDSCH and the DCI schedulingthe PDSCH is less than the predetermined threshold K.

As shown in FIG. 1 e , in the case where in a slot, the terminal detectsthe CORESET in multiple time-domain symbols and the potential PDSCHneeds to be cached, where the potential PDSCH denotes that the intervalbetween the PDSCH and the DCI scheduling the PDSCH is less than thepredetermined threshold K. In this case, the QCL parameter of the PDSCHis not acquired according to the QCL parameter of the CORESET having theminimum CORESET ID in the slot closest to the PDSCH (as shown in FIG. 1e , the QCL parameter of the PDSCH is not acquired according to the QCLparameter of CORESET0), but according to the QCL parameter of theCORESET having the minimum CORESET ID in the first 3 time-domain symbolsin the slot closest to the PDSCH (as shown in FIG. 1 e , the QCLparameter of the PDSCH is acquired according to the QCL parameter ofCORESET1).

As shown in FIG. 1 f , in the case where in slot n, it is determinedthat the base station schedules the PDSCH for the terminal, that is, inthis case, the interval between the DCI scheduling the PDSCH and thePDSCH is greater than the predetermined threshold K, and in slot n, thebase station further semi-statically configures the CORESET required tobe detected for the terminal. In this case, in one manner, it isstipulated that in the time-domain symbol where the PDSCH is located,the terminal does not need to receive and detect the CORESET in thistime-domain symbol in the case where the Spatial Rx parameter of theCORESET and the Spatial Rx parameter of the PDSCH are different, or theterminal and the base station stipulate that in this case, the DMRS ofthe PDSCH and the CORESET in the same time-domain symbol as the PDSCHare of QCL with respect to at least the Spatial Rx parameter.Alternatively, the terminal and the base station agree that in the casewhere the PDSCH and the CORESET are in the same time-domain symbol andthe receive beam corresponding to the Spatial Rx parameter of the PDSCHand the receive beam corresponding to the Spatial Rx parameter of theCORESET are different, the PDSCH and the CORESET are received throughthe receive beam corresponding to the Spatial Rx parameter of theCORESET.

Exemplary Embodiment Nine

In this embodiment, how to acquire the QCL parameter of the PDSCH in thecase where the PDSCH occupies multiple slots is described.

Firstly, one problem is that how to acquire the interval between thePDSCH and the DCI scheduling the PDSCH, which includes two acquisitionmanners described below.

In manner one of acquiring the time interval, the acquisition manner ofthe QCL parameter of the PDSCH is obtained according to one timeinterval between the starting symbol position of the PDSCH in the firstslot of A slots occupied by the PDSCH and the DCI and the predeterminedthreshold X1 (such as K; of course, the present application does notexclude the case where X1 and K are different). For example, if the timeinterval is less than the predetermined threshold X1, then the QCLparameter of the PDSCH is acquired according to the QCL parameter of aspecified CORESET (such as a CORESET having the minimum CORESET ID inthe slot) in the slot closest to the PDSCH; if the time interval isgreater than or equal to the predetermined threshold X1, then the QCLparameter of the PDSCH is acquired according to the informationindicated in the DCI, as shown in FIG. 4 b.

In manner two of acquiring the time interval, the acquisition manner ofthe QCL parameter of the PDSCH in each slot is obtained according to Atime intervals between the starting symbol position of the PDSCH in eachslot of A slots occupied by the PDSCH and the DCI and the predeterminedthreshold X1 (such as K; of course, the present application does notexclude the case where X1 and K are different). For example, in the casewhere the interval between the PDSCH in each of the first A1 slots andthe DCI is less than the predetermined threshold X1, then QCL parametersof the PDSCH in the A1 slots are acquired according to the QCL parameterof the specified CORESET (such as a CORESET having the minimum CORESETID in the slot) in the slot closest to the PDSCH; in the case where theinterval between the PDSCH in each of the last A2 slots and the DCI isgreater than or equal to the predetermined threshold X1, then the QCLparameters of the PDSCH are acquired according to the informationindicated in the DCI, as shown in FIG. 4 a.

The other problem is that there are two understanding manners of theacquisition which is performed according to the QCL parameter of theCORESET having a predetermined characteristic in the slot closest to thePDSCH.

In manner one of acquiring the QCL parameter, QCL parameters of thePDSCH in A slots are acquired according to the QCL parameter of theCORESET having the minimum CORESET ID in the slot closest to the firstslot of the A slots occupied by the PDSCH. The manner of acquiring theQCL parameters of the PDSCH in the A slots does not change, or the QCLparameters of the PDSCH in the A slots keeps unchanged.

In manner two of acquiring the QCL parameter, the QCL parameter of thePDSCH in each slot is acquired according to the QCL parameter of theCORESET having the minimum CORESET ID in a respective slot closest toeach slot of A slots occupied by the PDSCH. The manner of acquiring theQCL parameters of the PDSCH in the A slots may not be the same, or theQCL parameters of the PDSCH in the A slots may change.

Manner one and manner two of acquiring the time interval may arbitrarilycooperate with manner one and manner two of acquiring the QCL parameter.

In an embodiment, in the case where manner one of acquiring the timeinterval and manner one of acquiring the QCL parameter are adopted, asshown in FIG. 4 c , according to the time interval between the firstslot of 3 slots occupied by the PDSCH and the DCI is less than thepredetermined threshold K, the QCL parameters of the PDSCH in the 3slots are acquired according to the QCL parameter of the CORESET havingthe minimum CORESET ID in the slot closest to the first slot (that is,in slot n, the QCL parameter of CORESET0), and the QCL parameters of thePDSCH in the 3 slots keep unchanged.

In the case where manner one of acquiring the time interval and mannertwo of acquiring the QCL parameter are adopted, as shown in FIG. 4 b ,according to the time interval between the first slot of 3 slotsoccupied by the PDSCH and the DCI is less than the predeterminedthreshold K, the QCL parameters of the PDSCH in the 3 slots are acquiredaccording to the QCL parameter of the CORESET having the minimum CORESETID in the slot closest to each slot, and the QCL parameters of the PDSCHin the 3 slots may be different or may be the same.

In the case where manner two of acquiring the time interval and mannerone of acquiring the QCL parameter are adopted, as shown in FIG. 4 d ,according to the relationship between the time interval between eachslot of 3 slots occupied by the PDSCH and the DCI and the predeterminedthreshold K, it is determined that whether the QCL parameter of eachslot of the 3 slots is acquired according to the CORESET or according toinformation indicated in the DCI. In the case where the interval betweeneach of multiple slots of the PDSCH and the DCI is less than thethreshold K, the QCL parameters of the PDSCH in the multiple slots (thatis, slot n and slot n+1 in FIG. 4 d ) keep unchanged and the QCLparameter of the PDSCH is acquired according to the QCL parameter of theCORESET having the minimum CORESET ID in the slot closest to the firstslot of the multiple slots; in the case where the interval between thePDSCH in slot n+2 and the DCI is greater than K, the QCL parameter ofthe PDSCH in slot n+2 is acquired according to information indicated inthe DCI.

In the case where manner two of acquiring the time interval and mannertwo of acquiring the QCL parameter are adopted, as shown in FIG. 4 a ,according to the relationship between the time interval between eachslot of 3 slots occupied by the PDSCH and the DCI and the predeterminedthreshold K, it is determined that whether the QCL parameter of eachslot of the 3 slots is acquired according to the CORESET or according toinformation indicated in the DCI. In the case where the interval betweeneach of multiple slots of the PDSCH and the DCI is less than thethreshold K, the QCL parameter of the PDSCH in each slot of the multipleslots (that is, slot n and slot n+1 in FIG. 4 d ) is acquired accordingto the QCL parameter of the CORESET having the minimum CORESET ID in therespective slot closest to the each slot; in the case where the intervalbetween the PDSCH in slot n+2 and the DCI is greater than K, the QCLparameter of the PDSCH in slot n+2 is acquired according to informationindicated in the DCI. The interval between the PDSCH in each slot of the3 slots and the CORESET0 scheduling is determined. In the case where theinterval is less than K, the QCL parameter of the PDSCH is acquired byusing the QCL parameter of the CORESET having the minimum CORESET ID inthe respective slot closest to the each slot. In the case where theinterval is greater than K, the QCL parameter of the PDSCH is acquiredby using the QCL parameter indicated in the DCI. As shown in FIG. 4 a ,in slot n, the PDSCH is received by using the beam of CORESET0 in slotn; in slot n+1, the PDSCH is received by using the beam of CORESET1 inslot n+1; and in slot n+2, the receive beam in slot n+2 is determined byusing the QCL parameter indicated in the DCI transmitted in CORESET0 inslot n. The reason for this is that in K time-domain symbols, theterminal does not decode the DCI and needs to cache the PDSCH, and it ispossible that data may be scheduled for the terminal in CORESET0 in slotn and CORESET1 in slot n+1. Before the terminal does not detect the DCI,in slot n+1, the terminal needs to cache at least one of CORESET0 orCORESET1 for the PDSCH scheduled by the terminal. In the case where thereceiving capability of the terminal is limited, for example, terminalmay generate only one receive beam, the QCL parameter of the PDSCH ineach slot in the range where the interval between the DCI and the PDSCHis less than the predetermined threshold K is acquired by using theCORESET having the minimum CORESET ID in the slot closest to the PDSCHin the each slot.

In particular, in the case where the interval between the PDSCH and theDCI is greater than 1, whether A2 slots correspond to one set of QCLparameters (as shown in FIG. 4 e ) or whether each of A2 slotscorresponds to a respective set of QCL parameters (as shown in FIG. 4 f) is further agreed by the base station and the terminal or is notifiedby the base station through signaling information.

Which combination of the specific manner of acquiring the time intervaland the specific manner of acquiring the QCL parameter is adopted may beagreed by the terminal and the base station, or may be notified by thebase station through signaling information.

As shown in FIGS. 4 a to 4 d , K denotes 26 time-domain symbols and inslot n, the PDSCH scheduled by CORESET0 spans 3 slots, that is, {slot n,slot n+1, slot n+2}.

In FIG. 4 f , in the case where the interval between the PDSCH and theDCI are greater than two slots of the predetermined threshold K, the DCInotifies different QCL parameters for different slots, so that in theDCI, the QCL parameter corresponding to each slot needs to beconfigured. Of course, the present embodiment does not exclude that, thebase station configures a QCL parameter of one of multiple slots for themultiple slots in the DCI (such as configuring the QCL parameter in slotn+2, that is, configuring the QCL parameter in the first slot), the QCLparameters in other slots are configured through high-layer signaling,or the QCL parameters in other slots are obtained according to the QCLparameter configured by the DCI. For example, the polling manner isadopted in multiple slots. For example, there are only two sets of QCLparameters notified by at least one of the DCI or the high-layersignaling; and the PDSCH occupies 4 slots, and then the two sets of QCLparameters poll in the 4 slots. In FIGS. 4 a to 4 f , different QCLparameters correspond to different beams. The high-layer signaling maybe RRC signaling or may be MAC-CE command. The high-layer signaling maybe high-layer signaling used for notifying a candidate TCI state in theDCI. For example, in the case where the TCI in slot n+2 notified by theDCI is TCI state 2 (the TCI field notified in the DCI includes 3 bitsand corresponding to 8 active TCI states), the TCI state of the PDSCH inslot n+3 corresponds to TCI state 3.

In this exemplary embodiment, data may be transmitted repeatedly inmultiple slots occupied by one PDSCH, or different data may betransmitted in multiple slots.

Exemplary Embodiment Ten

In this embodiment, one state in the TCI field notified in the DCIcorresponds to multiple relationships; different relationshipscorrespond to different time units occupied by the PDSCH or differenttime unit sets; each relationship corresponds to one of the time unitsoccupied by the PDSCH or one time unit set; one relationship includesthe relationship between Z DMRS groups and Z RS sets; the Z DMRS groupsare in one-to-one correspondence with the Z RS sets; and the DMRS groupand the corresponding RS set, in the corresponding time unit or timeunit set, satisfy a QCL relationship with respect to QCL parameters.

Exemplary Embodiment Eleven

In this embodiment, in the case where the QCL parameter of thePDSCH/AP-CSI-RS is acquired according to the QCL parameter of theCORESET having the minimum CORESET ID in the slot closest to thePDSCH/AP-CSI-RS, it is to be further clear that the CORESET satisfies atleast one of the characteristics described below.

The CORESET having the minimum CORESET ID is the CORESET having theminimum CORESET ID in all the CORESETs required to be detected by theterminal included in a predetermined CC group in the time unit.

Exemplary Embodiment Twelve

In this embodiment, the QCL parameter of one CORESET is associated withwhether the first communication node detects a beam recovery responsesignal.

In an embodiment, the base station configures one CORESET for theterminal. When the terminal does not detect the beam recovery responsesignal, the base station notifies the QCL parameter of the CORESET tothe terminal through signaling. When the terminal needs to detect thebeam recovery response signal (for example, in 4 slots after theterminal transmits a beam recovery request signal to the base station,the terminal detects the beam recovery response signal of the basestation in the CORESET; in the case where the predetermined time windowis exceeded and the terminal has not successfully detect the beamrecovery response signal transmitted by the base station, the terminalstops detecting the beam recovery request signal in the CORESET), theQCL parameter of the CORESET is acquired according to the beam found bythe terminal in the beam recovery request signal transmitted by theterminal. As shown in FIG. 8 a , in T1 time period, the QCL parameter ofCORESET1 is acquired according to the signaling information notified bythe base station. In T2 time period, the terminal starts to detect, inCORESET1, the beam recovery request response signal transmitted by thebase station. The QCL parameter of CORESET1 is obtained according toreference signal indication information q_(new) included in the beamrecovery request signal transmitted by the terminal, where q_(new)denotes the reference signal indication information (that is, denotingthe beam newly selected by the terminal) selected by the terminal in anRS set. In T3 time period, the QCL parameter of CORESET1 is acquiredaccording to the signaling information transmitted by the base station,where in T1 time period and T3 time period, the signaling information ofthe QCL parameter with respect to CORESET1 transmitted by the basestation to the terminal may be different signaling information, that is,the base station may update the QCL parameter of CORESET1 in T2 timeperiod through the signaling information. The new beam found by theterminal in the beam recovery request signal transmitted by the terminalis obtained through the reference signal indication informationtransmitted by the terminal, where the reference signal indicationinformation denotes the reference signal selected by the terminal in anRS set. The reference signal includes at least one of a measurementreference signal or a synchronization reference signal.

In this exemplary embodiment, two reference signals are of QCL,indicating that the two reference signals are of QCL with respect to atleast the Spatial Rx parameter and whether the two reference signals areof QCL with respect to other QCL parameters is not limited.

In an exemplary embodiment, a channel may also be a signal, that is, thesignal is transmitted in the channel. For example, a data signal istransmitted in a data channel.

In an exemplary embodiment, different CCs may be associated throughdifferent serving cell IDs.
